Dual Angle Block Plane by Bridge City Tool Works
Instead of switching planes, you can flip the lever and easily flop the blade on this eminently deserving design. One side gives you a 47-degree general-purpose plane to shave with the grain, the other a shallower, 42-degree plane for stubborn end-grain work. Equally sharp? The body, milled from a single billet of stainless steel.
